pub fn from_sql_null(
    ty: &Type
) -> Result<Self, Box<dyn Error + 'static + Sync + Send, Global>>

Creates a new value of this type from a NULL SQL value.

pub fn from_sql_nullable(

type Err = ParseLsnError

The associated error which can be returned from parsing.

pub fn from_str(lsn_str: &str) -> Result<PgLsn, <PgLsn as FromStr>::Err>

Parses a string s to return a value of this type.

impl Ord for PgLsn

pub fn cmp(&self, other: &PgLsn) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<PgLsn> for PgLsn

pub fn eq(&self, other: &PgLsn) -> bool
